SPECIFICATION forming part of Letters Patent No. "?66,898, dated August9, 1904. Application filed June 23,1903. semi No. 162,794. (No model.)

To all whom it may concern:

Be it known that I, HEINRICH Pon'r'rnn, engineer, a subject of theEmperor of Germany, residing at KaiserVVilhelmallee 50, Dortmund,Germany, have invented certain new and useful Improvements in HorizontalCoke-Ovens, of which the following is a specification.

My invention relates to an improvement in horizontal coke-ovens providedwith vertical heating-flues, and has for its object to afford a moreuniform heating of the oven-walls by dividing asfar as practicable theheating-gases, as well as the heated air, led into the oven. Accordingto my invention the heating-gases are conducted simultaneously from bothovencrowns below on each side by a lateral piping and two branched-oifgas-pipes or more into two or several gas-dividing ports, which aredisposed below each other, so as to be mutually quite independent. Fromsaid gas-dividing ports the heating-gases pass through vertical nozzlesin the heating or combustion ports, in which they become mixed withstrongly-heated air and are then burned, whereby said gases during theirascension heat one-fourth or less of the oven-wall. @wing to thisdivision or distribution of the heating-gases onto two or several spaceswhich are completely separated or independent from each other, theresult is obtained that said gases flow out from all nozzles with thesame pressure, so that all the combustion-ports are uniformly heated.Further, as according to my construction the point of combustion of thegases can be set as closely as desirable to the bottom of the oven, andconsequently the path of the burning gases is as short as possible andalso the air is strongly heated, a quick and uniform carbonization ofthe coal to be coked is obtained.

In the accompanying drawings, forming a part of this specification, andin which similar letters refer to corresponding parts throughout theseveral views, two constructional forms of my improved coke-oven arerepresented.

Figure 1 is a vertical sectional view on the lines A A and B B of Fig.2; Fig. 2, a hori zontal sectional view on the lines E E, F F, and G Gof Fig. 1; Fig. 3, a vertical crosssection on the lines 0 G and D D ofFig. l, and Fig. i a vertical sectional view of a constructionalmodification of my coke-oven in which three gas-dividing ports insteadof two are provided.

The gases as they come back from the purifier plant are led from twomains a, Fig. i, lying along both sides of the group of ovens, throughnozzles a into the gas-dividing ports a lying beneath thecoking-chambers, Figs. 1 and 4:. Between said gasdividing ports a aredisposed partition-walls b in any desired number. If only onepartition-wall b is used, as to be seen in Fig. 1, section A A, twoindependent ports a are formed, while if, for example, twopartition-walls Z) are disposed, Fig. 4, three ports a are produced; butof course four partition-walls Z) or more may be provided. From theports a the gases pass in independent streams through vertical nozzles cin the combustion-port g. In the disposition shown in Fig. 1 two gasstreams are formed on each side, so that said gases are conducted intothe combustion-ports g in four independent streams. In the constructionrepresented in Fig. 4, however, three independent gas streams areoriginated on each side, so that the gases are led in six independentstreams to the combustion-ports g.

The combustion air passes through the vaulted channel (Z and the lateralports d (Z in the space a, situated beneath the bottom port proper.Thence the combustion-air is conducted through the numerous openings (1*into the spaces cl, wherefrom said air passes through the annularopenings 0 between the nels a nozzles 0 adapted to lead the heatinggasesto the combustion-fines, air-fines (Z (Z (Z (Z openings (1* for thepassage of said air,

s aces (Z and annular assa 'es 6 between said 7 b for the passage ofsaid air, spaces (Z and annular passages 0 between said nozzles 0 andthe ceiling f, said passages 6 being adapted to lead the air to thecombustion-ports in order to be mixed With said heating-gases,substantially as set forth.

In Witness whereof I have hereunto signed my name, this 6th day of June, 1903, in the presence of tWo subscribing Witnesses.

HEINRICH POETTER.
